Excuse me if I'm not doing something right on the site it's my first time here (have used stackoverflow before). I have a centos 5.2 server running Plesk and the tech support guys are refusing to look into this as they keep saying that I should just reboot, however that's not really a solution as it's happening a lot (perhaps once a week).
I have to admit I'm not hugely into Linux but I know my way around and here's what the syslem messages say for just before the server went down, can someone perhaps confirm my suspicion that this is a lack of RAM thing?
